Description

  The present invention relates to an alarm display device for notifying an operator that an abnormality has occurred in a plant in a plant monitoring system such as a thermal power plant.

  For example, in a power plant, an alarm display device that monitors the plant by displaying alarm information on an alarm display screen when the plant is abnormal is employed.

  In the conventional alarm display device, when an alarm is generated, an operator knows the point of alarm generation, the content of the alarm, and the like by sequentially switching the screen display by selecting an interactive display menu on the display screen. For example, the operator can switch from the plant monitoring screen to the alarm display screen, display the alarm message screen, check the alarm message, display the alarm window information corresponding to the plant monitoring point, search the plant monitoring screen related to the generated alarm, Display trend graphs and system diagrams related to alarms sequentially. As described above, since all the display of the related screen necessary for the alarm display is based on the selection operation of the interactive display menu, there is a problem that the operation load on the operator becomes large.

  In addition, since the power plant is large and complex, there are many monitoring points in the plant monitoring system that detect abnormalities in the plant and notify the operator, and there are a wide variety of alarm items. There is.

  For such a problem, for example, an alarm display device used in a plant monitoring system of a power plant shown in Patent Document 1 aggregates a plurality of plant monitoring points on a part of the display screen. Forming multiple groups and providing a display area to display a group of alarm windows that display each group. When an alarm occurs during plant monitoring, the alarm window changes its display status by color, flicker, etc. By giving it, the operator can easily detect the alarm.

Japanese Unexamined Patent Publication No. 2000-112521 (5th page, FIGS. 1 and 2)

  The alarm display device used in the plant monitoring system of the power plant shown in Patent Document 1 switches the display screen in multiple stages by selecting menu items on the dialog screen for various alarm items in the alarm window where the alarm occurred. As a result, there is a problem that it takes a long time to read out the alarm contents from the alarm occurrence, and it is impossible to respond quickly.

  In addition, when a large number of alarms are generated, it is necessary to switch display of a large number of alarm items and check the target alarm items, which causes a problem that the burden on the operator is heavy and an operation error is likely to occur.

  This invention has been made to solve the above-mentioned problems, and even in the event of frequent alarms, the plant status and necessary response measures can be quickly grasped and confirmed reliably for multiple alarm items. An object is to obtain an alarm display device capable of processing.

The alarm display device according to the present invention,
